any prototypes of first party games developed by Nintendo or Microsoft

any prototypes from known illegal sources, such as hacking, unauthorized downloads, etc. Only prototypes originating from physical media are allowed

It is fine to write articles about them, but it is not allowed to upload prototypes of them. Any violations will be removed.

Prototype information

Game name:

Choose the game name wisely. Try to choose the canonical game name. Take care to use the proper casing. When in doubt, google it and use the same one Wikipedia or Giant Bomb uses. Please use the search function to check if the article doesn't exist already.

The article name will be: Game name (prototype).

Prototype name:

The convention we use is as follows (use the most descriptive name available; choose the first one, if not available, then the second one, etc.):

Use the name that describes where the prototype came from or its purpose, especially if this is the name used in other places.

If there are two prototypes of the same game on the same day, mark the second B, the third C etc.

e.g. Metal Head (Dec 7, 1994 prototype B)

For cartridge/EPROM prototypes, often there is a label with a date, usually a month and a day. The year can often be guessed from the final release date and the state of completion of the prototype.

For disc prototypes, this is usually a mix of these:

The disc header date (if the disc contains a header).

The primary volume creation date at:

0x963d of the first track on raw 2352 (bin/cue) dumps.

0x832d of the first track on 2048 (iso) dumps.

The latest file modification date on the disc(s).

Beware of early platforms like Sega CD and Sega Saturn, where CD-Rs were burned manually and often had faked volume creation and file modification dates. This is usually the case if all the files are the exact same date/time and/or have a suspiciously "round" date/time, like Jan 1, 1995 00:00:00.

Sometimes executables on the disc(s) contain build dates.

Use the month and year, if the specific day is unavailable.

e.g. Ecco: The Tides of Time (Apr 1994 prototype)

If the build date is unknown, or suspicious, use any extra information that can identify the prototype from others.

e.g. Aero the Acro-Bat (PAL prototype)

If all else fails, just use Game Name prototype.

e.g. Lobo (prototype)

If you are not sure what to do, use this convention and don't worry, we will modify the article accordingly.

The build date(s) of the final version(s) of the game, if available.Example: {{RegionDate|JP|Aug 6, 1993}} {{RegionDate|EU|Aug 27, 1993}} {{RegionDate|US|Oct 12, 1993}}

Final release date:

The release date(s) of the final version(s) of the game, if available.Example: {{RegionDate|JP|Dec 20, 1991}} {{RegionDate|US|1992}} {{RegionDate|EU|Unreleased}}

Unreleased:

Check if the game was unreleased in all regions.Do not check if a final release date is provided above.

File for download

Upload an archive (.zip preferred for ROMs, .7z/.rar for disc images) of the prototype, if applicable. Please keep the file name consistent with the article page title, if possible. Note, there is currently a 100MB upload limit on this page. If the file you wish to upload is larger, please use the other uploader.
